Description
Technical field
The utility model is related to power outlet field more particularly to a kind of sockets and protection door with protection door.
Background technology
Socket with protection door is internally provided with the protection door for preventing getting an electric shock, and when socket is not inserted into, insulating materials is made
Protection door can shelter from the electrode of socket, can prevent from mispluging electric shock；When socket is inserted into, protection door can automatically open, with
Just plug is inserted into.General technology is preferable and meets the protection door of national standard, need to use the insertion design of anti-monopole.
The anti-monopole insertion of three-terminal polarized plus plug is generally there are two types of design, first, earthing pole (i.e. E poles) unprotect door, L poles, N poles
The two poles of the earth will also be inserted into the open-top protection door of ability simultaneously, but it can not limit the insertion of the three-terminal polarized plus plug of earthing pole missing, it is impossible to
The safety ground of electric appliance is enough realized, so as to which security risk can be brought；Second is that there are protection door in three poles, in the open-top protection of grounding pin
Men Shi, L pole, N poles the two poles of the earth protection door can just be opened.And the latter can open safety using screwdriver or key insertion earthing pole
Door, causes that L poles and N poles sleeve are exposed, and there are security risks.
China Patent No. is CN201120295572.9, authorized announcement date is on 2 22nd, 2012, entitled " a kind of

Limit guide rail 21 and anti-list insert block 22.
Three pole protection door 4 is mounted in the back box 2, and three pole protection door 4 includes main body 44, the main body 44
One first protection portion 41 is set along the first direction, and first protection portion 41 is provided with a groove 411, and the groove 411 is separate
One end of main body 44 is provided with the 3rd jack 4112 of earthing pole driving inclined-plane 4111 and earthing pole；The main body 44 is in a second direction
It is symmetrical arranged one second protection portion 42 and one the 3rd protection portion 43, second protection portion 42, the 3rd protection portion 43 is distinguished
With the first protection face 45, the second protection face 46, second protection portion 42,43 side of the 3rd protection portion are also set respectively
There is anti-list to insert groove 47.
The protection door limit guide rail 21 that three pole protection door 4 is corresponded in back box 2 is additionally provided with sliding slot so that protects three poles
Door 4 can slide in back box 2 along protection door limit guide rail 21.One end of three pole protection door 4 is connected with two resetting springs
5, the other end of the resetting spring 5 is connected in bipolar protection door 3.
3 middle part of bipolar protection door is engraved structure, is provided with the second jack of earthing pole 31, the bipolar protection
Door 3 is provided with protection face 32, and 3 side of bipolar protection door is provided with anti-list and inserts groove 33.
When plug is not inserted into socket, the ground connection of the bipolar protection door 3 of 11 face of the first jack of earthing pole on cover board 1
The earthing pole driving inclined-plane 4111 of pole the second jack 31 and three pole protection doors 4；The protection of the bipolar bipolar protection door 3 of 12 face of jack
Face 32；First protection face 45 of three pole jacks, 13 face, three pole protection door 4.
First protection face 45 can stop that plug electrode is inserted into；The earthing pole driving inclined-plane 4111 and second
Protection face 46 can stop that plug electrode is inserted into, and be moved when can also be by the insertion of electrode, can with but be not restricted to
Inclined-plane, concave curved surface, convex surface etc..
When three-terminal polarized plus plug is inserted into socket, since earthing pole is longer than other the two poles of the earth, it is initially inserted into jack, plug
Earthing pole touches three poles through the first jack of earthing pole 11 and the second jack of earthing pole 31 of bipolar protection door 3 on cover board
The earthing pole driving inclined-plane 4111 of protection door 4 promotes earthing pole driving inclined-plane 4111 to move, so as to drive three pole protection doors 4 whole
Body moves forward, at this point, the second protection portion 42 of three pole protection doors 4 and the first protection face 45 of the 3rd protection portion 43 leave face
Cover board 1 on three pole jacks 13 move forward, and the second protection face 46 of the second protection portion 42 and the 3rd protection portion 43 is gradually
The three pole jacks to align on cover board 1；When the earthing pole of plug is inserted into enough depth, the earthing pole of plug leaves earthing pole drive
Dynamic inclined-plane 4111, into the 3rd jack 4112 of earthing pole, at this time in three pole jacks of the receiving electrode contact pin insertion cover board 1 of plug,
It is contacted with the second protection face 46 of the second protection portion 42 and the 3rd protection portion 43, plug continues to be downwardly into, the receiving electrode of plug
Contact pin promotes the second protection face 46 of the second protection portion 42 and the 3rd protection portion 43 to move forward, and exposes under three pole protection doors 4
Electrode, the contact pin of plug is smoothly inserted into.When pulling the plug out of the socket, due to the effect of resetting spring 5, three pole protection doors are returned to initially
Position.
When the plug of earthing pole incompleteness is inserted into socket, since its earthing pole is incomplete, the receiving electrode contact pin of plug is directly inserted
Enter into three pole jacks 13 of cover board, at this point, the first protection face 45 of three pole jacks, 13 face, three pole protection door 4, due to first
Protection face 45 does not possess the function of being promoted, therefore three pole protection doors 4 will not move, so as to prevent continuing into for plug.
When the extremely incomplete plug of receiving electrode wherein one is inserted into socket, since earthing pole is longer than receiving electrode, it is initially inserted into slotting
Kong Zhong, the earthing pole of plug pass through the second jack of earthing pole 31 of the first jack of earthing pole 11 and bipolar protection door 3 on cover board,
The earthing pole driving inclined-plane 4111 of three pole protection doors 4 is touched, earthing pole driving inclined-plane 4111 is promoted to move, so as to drive three poles
Protection door 4 is whole to be moved forward, at this point, the second protection portion 42 of three pole protection doors 4 and the first protection face of the 3rd protection portion 43
The 45 three pole jacks 13 left on the cover board 1 of face move forward, and the second guarantor of the second protection portion 42 and the 3rd protection portion 43
The three pole jacks that mask 46 gradually aligns on cover board 1；When the earthing pole of plug is inserted into enough depth, the earthing pole of plug from
Earthing pole driving inclined-plane 4111 is opened, into the three of the 3rd jack 4112 of earthing pole, at this time the receiving electrode contact pin insertion cover board 1 of plug
It in the jack of pole, is contacted with the second protection face 46 of the second protection portion 42 or the 3rd protection portion 43, due to the incompleteness of contact pin, three poles are protected
Shield door 4 can be tilted to the one side for having contact pin, and the anti-list that the anti-list of 43 side of the 3rd protection portion is inserted groove 47 and can be blocked in back box 2 is inserted
Block 22, so as to which three pole protection doors 4 be prevented to continue to move along, so as to which the electrode under it cannot be exposed.
From the foregoing, it will be observed that the utility model proposes socket protection door structure, three poles of pin incompleteness are can effectively prevent
Plug is inserted into socket.
Embodiment described above only expresses the several embodiments of the utility model, and description is more specific and detailed
Carefully, but it should not be interpreted as limiting the scope of the present invention.It should be pointed out that for the general of this field
